Description
The upstream port for this information line.
Lists the status of the port. Valid states are down if frequency is
unassigned or admindown if the port is shut down. If the port is up,
this column shows the center frequency of the channel.
The rate that station maintenance polls are generated (in
milliseconds).
The number of missing polls, per codeword/FEC block.
The number of polls in the sample, per codeword/FEC block.
The ratio of missing polls to the number of polls, expressed as a
percentage.
The level that the missed poll percentage must exceed to trigger a
frequency hop, expressed as a percentage.
The maximum rate that frequency hopping will occur (in seconds).
The number of correctable forward error corrections (FEC) errors
on this upstream port, per codeword/FEC block.
The number of uncorrectable FEC errors on this upstream port, per
codeword/FEC block.
